just go back to the 1970's and go decade by decade. see what china has accomplished. going from a basket case to the third and soon to be the second biggest economy. the 2 way trade between korea-china, japan-china is now bigger then korea-us, japan-us. a lot of countries is looking to sell to a country whose citizen can paid with real cash (yuan) and not USD (toilet paper). it feels strange and uncomfortable to most americans but you are only in the 2nd decade of the china century. the gdp of the 2 country will cross in 2-3 decades, a lot faster if yuan doubles.
